Recent research showed that precision medicine can identify new treatment strategies for patients with childhood cancers. However, it is unclear which patients will benefit most from precision-guided treatment (PGT). Here we report consecutive data from 384 patients with high-risk pediatric cancer (with an expected cure rate of less than 30%) who had at least 18 months of follow-up on the ZERO Childhood Cancer Precision Medicine Program PRecISion Medicine for Children with Cancer (PRISM) trial. A total of 256 (67%) patients received PGT recommendations and 110 (29%) received a recommended treatment. PGT resulted in a 36% objective response rate and improved 2-year progression-free survival compared with standard of care (26% versus 12%; P = 0.049) or targeted agents not guided by molecular findings (26% versus 5.2%; P = 0.003). PGT based on tier 1 evidence, PGT targeting fusions or commenced before disease progression had the greatest clinical benefit. Our data show that PGT informed by comprehensive molecular profiling significantly improves outcomes for children with high-risk cancers. ClinicalTrials.gov registration: NCT03336931.
最近的研究表明,精准医学可以为儿童癌症患者确定新的治疗策略。然而,目前尚不清楚哪些患者将从精准指导治疗(PGT)中获益最大。在这里,我们报告了连续 384 名患有高危儿科癌症(预期治愈率低于 30%)患者的随访时间至少为 18 个月的结果,这些患者均参加了 ZERO 儿童癌症精准医学计划 PRISM 试验。共有 256 名(67%)患者接受了 PGT 推荐,110 名(29%)患者接受了推荐的治疗。PGT 导致客观缓解率提高了 36%,与标准治疗(26%比 12%;P=0.049)或未根据分子发现指导的靶向药物治疗(26%比 5.2%;P=0.003)相比,2 年无进展生存率得到了改善。基于 1 级证据的 PGT、针对融合的 PGT 或在疾病进展前开始的 PGT 具有最大的临床获益。我们的数据表明,基于全面分子分析的 PGT 显著改善了高危癌症患儿的预后。临床试验注册:NCT03336931。
